Table 5.

Results of LRP on the ERP autoencoder when keeping the distance layer input constant as in Kauffmann et al. (2020b) and when allowing a gradient flow.

XAI Variant ROC Cos
LRP Constant 65.3 (20.5) –22.0 (13.9)
LRP Gradient 88.0 (12.8) 62.2 (19.2)

Performance improves significantly when breaking the conservation property and allowing gradient flow.
